FAQ
When is Hongdae least crowded?
Today’s forecast marks 10:00, 11:00, 12:00, 13:00 as relaxed or moderate, and 17:00, 18:00, 19:00 as crowded. The pattern repeats most days: mornings before 11:00 are the quietest window for tourist districts, evenings the busiest.
How is the crowd level measured?
The City of Seoul estimates the number of people in each area from mobile-network and sensor data and publishes it every five minutes with a four-step level (relaxed · moderate · somewhat crowded · crowded) and a forecast for the coming hours. This page reads that feed.
Does "crowded" mean I should avoid it?
Not necessarily — markets and Hongdae are lively because they are crowded. Use the forecast to time palaces, museums and cafés, where a queue actually costs you time.
